Analyzing short-range correlations through the nonlocal dispersive optical model
ORAL
Abstract
The presence of short-range correlations in nuclei leads to a population of nucleons with momentum greater than the nuclear Fermi momentum. This high-momentum content manifests in the tail of nucleon momentum distributions which can be calculated using a nonlocal dispersive optical model (DOM). We have generated DOM self-energies for three nuclei, $^{40}$Ca, $^{48}$Ca, and $^{208}$Pb. Using these self-energies, we explore how short-range correlations effect quantites such as particle number, neutron skin, and particle distributions, thereby providing insight as to how the role of short-range correlations varies with the size and asymmetry of nuclei. Furthermore, the existence of high-momentum content depletes the single-particle strength below the Fermi momentum. This effect is studied by calculating the spectroscopic factors from these DOM self-energies that reproduce $(e,e'p)$ momentum distributions.
